hydranencephaly/fever

During the 1974/75 lambing season numerous reports were received from various parts of the Republic of South Africa and South West Africa of severe abdominal distension in ewes after vaccination with the attenuated Rift Valley fever and/or attenuated Wesselsbron disease vaccine. The ewes were

A 5-fluorouracil mutagenised Rift Valley fever virus strain, which was shown to be attenuated and immunogenic in cattle and sheep, was evaluated for its ability to cause teratogenic effects in pregnant sheep. A group of 50 sheep at various stages of pregnancy was inoculated with the virus and the

This paper describes the causes of death of 54 maras (Dolichotis patagonum) in a captive colony in Mexico over a period of seven years. There were 35 adults, 11 juveniles, five neonates, two fetuses and one stillbirth--27 males, 21 females and six whose sex was not determined. Trauma was the cause

Various viruses relating to congenital brain teratology in ruminants are discussed. These include: bluetongue which may be responsible for porencephaly and hydranencephaly; Akabane disease, Rift Valley fever (mouse brain attenuated virus) and Wesselsbron disease (wild-type and mouse brain attenuated

In late 2011 a novel virus of the Simbu serogroup, family Bunyaviridae, genus Orthobunyavirus, was discovered at the German-Dutch border and named "Schmallenberg virus" (SBV). Since then, the virus has spread rapidly to other European countries, and the involvement of biting midges has been

BACKGROUND The present study describes the pathologic changes in the brain and the spinal cord of aborted, stillbirth and deformities of newborn lambs infected with viral agents. METHODS From February 2012 to March 2013, a total of 650 aborted fetuses from 793 pregnant ewes were studied from 8

A fresh isolate of Akabane virus was inoculated intravenously into 11 seronegative pregnant cows at 62 to 96 days of gestation. Two of the cows were slaughtered 18 days post-inoculation, and the fetuses were examined; the remaining cows were allowed to give birth. All the inoculated cows developed

We generated a recombinant Akabane virus (AKAV) expressing enhanced green fluorescence protein (eGFP-AKAV) by using reverse genetics. We artificially constructed an ambisense AKAV S genome encoding N/NSs on the negative-sense strand, and eGFP on the positive-sense strand with an intergenic region

In Autumn 2011, nonspecific clinical signs of pyrexia, diarrhoea, and drop in milk yield were observed in dairy cattle near the German town of Schmallenberg at the Dutch/German border. Targeted veterinary diagnostic investigations for classical endemic and emerging viruses could not identify a

Schmallenberg disease has emerged in North-Western Europe in 2011 and has since spread widely, even across the European borders. It has the potency to infect many, mainly ruminant, species, but seems to lack zoonotic potential. Horizontal transmission occurs through various Culicoides biting midges
